Key Features
- 100-position dual-row shielded board stacking connector on 0.50 mm pitch with 4.0 mm nominal stack height for ultra-compact mezzanine designs
- Integrated EMI shielding (S suffix) reduces crosstalk and radiated noise on high-speed differential pairs above 1 GHz
- Gold-plated termination contacts and kinematic keying (K suffix) ensure low contact resistance below 30 mΩ and mis-mating prevention in automated assembly
Applications
The LSHM-150-04.0-H-DV-A-S-K-TR is designed for high-speed board stacking applications in wireless communications modules, compact camera systems, and industrial IoT gateways where a 4.0 mm stack height constraint and EMI shielding are both required. Its 100-position dual-row layout on 0.50 mm pitch delivers sufficient signal bandwidth for USB 3.0, PCIe, MIPI CSI-2, and LVDS interfaces between stacked boards in space-constrained enclosures. Tape-and-reel packaging enables seamless automated SMT placement in high-volume consumer electronics manufacturing.

Frequently Asked Questions
What stack height does the LSHM-150-04.0-H-DV-A-S-K-TR provide, and how does its 0.50 mm pitch compare to alternative board stacking connector series?
The LSHM-150-04.0-H-DV-A-S-K-TR provides a 4.0 mm nominal board-to-board stack height with contacts on 0.50 mm pitch. Compared to SAMTEC's BTH series on 0.80 mm pitch for similar position counts, the 0.50 mm pitch reduces the connector footprint by 37% per row — enabling a 100-position interface within a body length of approximately 29 mm (1.169 inch as specified) versus over 45 mm required at 0.80 mm pitch.
How does the integrated EMI shielding on the LSHM-150-04.0-H-DV-A-S-K-TR protect high-speed signals in a stacked PCB assembly?
The S (shielded) suffix on the LSHM-150-04.0-H-DV-A-S-K-TR means the connector includes a metal shield surrounding the contact array, providing a continuous ground reference that attenuates EMI coupling between adjacent differential pairs and external radio interference. At signal frequencies above 1 GHz — typical for USB 3.0 at 5 Gbps or PCIe Gen 1 at 2.5 Gbps — unshielded connectors can add 10–20 dB of inter-pair crosstalk, whereas a shielded alternative maintains crosstalk below -30 dB for cleaner eye diagrams.
For a camera module design needing MIPI CSI-2 lanes, how many differential pairs can the LSHM-150-04.0-H-DV-A-S-K-TR accommodate?
With 100 total contacts in a dual-row layout at 0.50 mm pitch, the LSHM-150-04.0-H-DV-A-S-K-TR can support up to 20 differential pairs allocated to MIPI CSI-2 data and clock lanes — far exceeding the 8-lane maximum of MIPI CSI-2 v2.0. The remaining contacts carry control signals, I2C, power (up to 0.5 A per contact), and ground returns, making it a single-connector solution for 4-lane or 8-lane high-resolution camera interfaces running at 1.5 Gbps per lane.
